Whoever annoys Allah and His Messenger , is cursed in this World and the Hereafter Here,

Allah warns and threatens those who annoy Him by going against His commands and doing that which He has forbidden, and who persist in doing so, and those who annoy His Messenger by accusing him of having faults or shortcomings -- Allah forbid. `Ikrimah said that the Ayah:

إِنَّ الَّذِينَ يُؤْذُونَ اللَّهَ وَرَسُولَهُ

Commentary

In the previous verses, Muslims were warned against doing what caused pain to the Holy Prophet ﷺ . But, some Muslims used to get involved into doing such things unintentionally simply because of their lack of knowledge or attention. For example, walking into his living quarters without having been invited or, in the event of an invitation to eat at the house, coming in and sitting there much earlier than the time set for it or, once the meals were over, just keep hanging at the house talking to each other and keep delaying their due departure. Upon this, a warning has been served in the verse: يَا أَيُّهَا الَّذِينَ آمَنُوا لَا تَدْخُلُوا بُيُوتَ النَّبِيِّ (0 those who believe, do not enter the houses of the Prophet - 33:53). This was the pain caused to the Holy Prophet ﷺ without any volition or intention, simply by negligence. On this, only a warning was considered sufficient. Mentioned in the two verses cited above is the pain that was caused to him intentionally by the disbelievers and hypocrites. It is for this reason that Maulana Ashraf Thanavi (رح) has parenthetically added the word: قَصدَاً (qasdan: intentionally) at this place in his abridged summary which includes many a physical pain caused to him at the hands of disbelievers on different occasions as well as the emotional ones that were caused to him in the form of taunts and insults and false accusations against his blessed wives. The cited verses also gives a warning of Divine curse and punishment to those who cause such pains to him by intention.
